Just wondering. Do any of your users have multiple SMTP addresses such as and assigned?

You can only send as in the from field using the primary SMTP address which is by design.

I recommend you to rebuild the GAL because I had this issue before, According to Microsoft the SEND-AS permission is AD attribute and Exchange uses GAL to retrive the users properties.
I rebuild the GAL and it workes ifne for me :)
